I was in the right place at the right time as the Nissan Deltawing driven by Gunnar Jeanette came under the bridge at turn 11. The problem was in this case, he was coming under the bridge with no wheels on the ground! He had just been clipped by the Green Porsche and became airborne.

The Delta E-4 Coupe is a very compact, light weight, low drag, 4-seat passenger car that the company has been working on since 2007.
The idea behind this model was to build an ultra low energy vehicle, and not just a vehicle that provides low emissions.
The company feels that any car can provide low emissions if run on batteries, but bigger automobiles - like the Audi Q7 or the BMW X5 - will still be depleting energy at a much faster rate than smaller, more lightweight vehicles.
They go on further to explain that automakers, after creating all of these low emissions vehicle, will eventually have to focus more on reducing the energy used by these models.

Enter the E-4 Coupe.

It may not be the prettiest vehicle we’ve ever seen, but it is certainly impressive nonetheless with a carbon composite chassis that weighs only 187 lbs and high performance direct-drive electric motors that together can get the E-4 all the way up to a top speed of 150 mph.
Want fast results?
The E-4 Coupe can get from 0-60 mph in under five seconds.

Get ready folks, the electric car phenomenon has just taken its next step.
